Bis(μ-hydroxido-κ2O:O)bisbis(5-car­boxy­pyridine-2-carboxyl­ato-κ2NO2)iron(III) dihydrate

摘要

The complete binuclear complex in [Fe2(C7H4NO4)4(OH)2]·2H2O, is generated by the application twofold symmetry. The Fe^III atom is coordinated by the O atoms of two bridging hydroxyl groups and by two N and two O atoms from two pyridine-2,5-di­carboxyl­ato ligands, forming a distorted octa­hedral geometry. The Fe⋯Fe separation within the dinuclear complex is 3.0657 (4) Å. In the crystal, O—H⋯O and C—H⋯O hydrogen-bonding inter­actions connect the mol­ecules into a three-dimensional supra­molecular network.
